We have an existing application on SoundCloud that was created some time ago and set up to use OAuth1. Recently we needed to expand SoundCloud-related functionality and, because of some problems with the old library, had to upgrade to new cocoa-api-wrapper library that uses OAuth2 client.

The problem now is that we cannot access our application with its key/secret because of the different version of OAuth. While it is possible to set up new application and get new key/secret pair, we wouldn't want to lose all the data associated with the current application.

Is there a way to have the same SoundCloud application accessible with both versions of OAuth (OAuth1 is still being used)? If not, what's the best way to handle this situation?
